a the following description, in connection with the accompanyingdrawings, is 'a specification, like reference characters on lthe draw'-ings indicating like parts in theseveral This invention relates to buingmachines and is herein illustrated in connection with a. `machine forbuliing'parls of boots and In machines of this class it has beencustomary to pass the stock, for example counters, box toes, etc.,`betweena feed roll and-a buiin roll which are located approximately int e mouth of a suction conduit and to provide in the rear of the rollsabrush to remove from the bufi'ed Stock the dust generated during thebuiiing operation. With this construction, however, theremoval of dusthas been ,incomplete since a certain amount of dust clings to the buffedsurface despite the action of the brush and is therefore not.inposition' to be swept out by the'current of'a1r. Moreover, from theAfact that the brushhas been arranged in proximityl to the buiiing roll,the current of air produced by the suction apparatus has been blocked atjust the should have been permitte free passage.

In-order to remedy these'and other defects, one 'feature of the presentinvention consists in la machine of the class described of a strikerarranged to deliver upon the buied article va series of blows whichserve tov disengage thev dust from .the surface ofy the article and toraise it into position to be 'swept away. This striker may be placed inlbutling' roll is but momentary.

Another feature of the r`invention consists of a perforated' guidearranged at an angle -Specicationof Letters Patent. Applicationle'dMarch 7 1913. Serial No. 752,752. i

it back toward the operator into position .to be readily removed fromthe mach-ine.

These and other features of the invention, including certain details ofconstruction and .combinations of parts will be set forth in connectionwith an illustrativemachinc and pointed out inthe appended claims.

Referring now to the accompanying drawings,-l1`igure 1 is a longitudinalvertical sectionv through a machine in which the present invention isembodied; Fig. 2 is a front elevation of the machine, and Fig. 3 is aside elevation of the machine.

The butiing roll l, herein shown as-a split. roll, is fast to a shaft.v3 which is rotatably mounted in slidable bearings the positions of whichmay be controlled by adjusting screws one of which is shown at 5. Thefeed` roll 7 which has a facing of rubber or other yielding material isfast to a shaft 9 which is rotatable in fixed bearings. The plane which`includes the axes of both rolls is inclined; and, slidably mounted uponthe frame of the machine, ina plane parallel to this one, is a late 11which is adjustably heldbetween tlie upper pair of screw bolts 13 andthe lower pair of screw 'bolts 15 so that the position ofsaid plate maybe ad# justed for a purpose presently to be de-v scribed.v A presser 17which extends in a direction oblique to the direction of feed and withina short distance of the bite of the rolls is adjustably held in positionon the plate 11' by screws .19 which pass through l by the mouth of asuction conduit, said condnit'heing connected with a suction apparatus27 of any approved type the kmovable Patented Nov. 11, 1913.

cylindrical brush. Belowthestriker aud rolls is a perforated gu1de`37arranged at an angle to deflect the piece of lstock after "it haspass-fed' the-'striker and turn it back toward `-the front of themachine in position to be removed readily. Thisguide has `flaring wingsasshown in Fig. 2 and fills the lower portion of the mouth of the dustcony duit. being fastened to the side walls of said conduit by screws 3Swhich pass through carsl ou said guide and into said walls. The upperwall 23 of the suction conduit forms a' cover which pivoted to the frameat 37, and adjustably mounted on bosses on this cover is a plate 40. Abuiiing roll operated at high speed carries with it in its revolulion acloud of dust. a portion of which is ".lected .l'roll'i the fronty oil'the u'lachiue. The plate l0 is 'adjusted as close aspossible to theperiphery of the roll 1 and serves to dctlect this moving cloud anddirect the dust into the suction conduit. It also serves by closing thespace between the roll and the hinged cover to concentrate the draft.

'Referring now to Figs. 2 and 3, the shaft 3 upon which the buiiing rollis mounted carries a pulley 41 over which and over a pulleybristlesandvconsisting of a segment of al 413 on the counter-shaftltdpasses a belt 47,'

a belt tightener 49 operate by a handle 51 .being provided formaintaining the tension 'on said belt. On the shaft 29 of the fan is apulley 53, and on the shaft 31 of the striker is a pulley 55, saidpulleys being driven by a belt 57 which passes around said pulleys andaround a pulley 59 on the counter-shaft, a belt tightener 61 operated bya handle 63 being provided around which the belt 57 also passes'. Fromthe connections indicated above it will be evident that the buflingroll, the striker and the fan will all be rot-ated at a speed greaterthan that of the counter-shaft 45. In practice the buiiing roll isrotated at from 3000 to 4000 revolutions per minute.

Thel feed roll is driven at comparatively low speed by the followingmechanism:

Fast to the counter-shaft fifi-is a sprocket 61 around which and arounda sprocket 63 on a shaft 65 passes a chain 67. On one end' of shaft 65is a small gear 69 which meshes-with a large gear 71 on one end ofanother shaft 73 the other end of which carries a small sprocket 75; andaround the last named sprocket and a sprocket 77 on the shaft 9 of thefeed roll passes a chain 79.

A A roll Slearried by an adjustable bracket serves totighten this chain;anda similar roll 83, similarly mounted, serves to tighten the chain 67.y

In the operation of the machine the plate 1l is properly adjusted andthe presser 17 set with reference to the thickness ofthe stock so as toleave between the surface of the feed roll and the operative surface ofthe presser a space the width of which is less lthan that ofthe stock tobe buffed. Power is then vapplied to the counter-shaft therebyr rotatingthe boiling roll, the striker and the fan at high speed and the feedroll at comparatively low speed. The pieces of stock arev fed 'one byone to the machine. Each piece of stock is gripped between the presser'and the yielding surface of the feed roll'by being pressed into saidyielding surface. The stock is thus firmly held while the b'ufiing rollrotat-ing at high speed buffs said stock.v As the forward end of thepiece of stock emerges from between the rolls and approaches the shaft31 a rapid succession of blows is delivered upon it by the striker 35 sothat the forward portion of the stock raised in position to be carriedaway by the suction apparatus. As the stock continues to be advanced,its forward end presently encounters the inclined perforated guide 37and is deflected outwardly toward the operator.

I have found the striking or tapping of the free end of the stock veryeffective as compared with a uniform brushing action. The successivesharp blows effectively raise the dust which normally clings to thebufed surface of the stock and would not belthoroughly removed by theaction ofthe usual cylindrical brush. I have found, however, that thedesirable effects of both the'striker and an ordinary cylindrical brushmay, be secured by forming the striker as illustrated, as asegment of acylindrical brush and using very stiftl bristles which yield as a wholevery slightly if at all.

Although the invention has been set forth in connection with aparticular machine it should be understood that the invention is notlimited in the scope of its application to the particular machine shownand described.

Having thus described my invention, what I claim and desirelto secure byLetter Patent of the United States is 1. A machine of the classdescribed having, in combination, a buiing' roll, means for feedingstock to said roll, and means for viplratmg the stock after it haspassed said ro l 2.
